Overall it was fun and great to stay in Evan's accommodation, we were coming very late from Suvarnabhumi Airport (around 11 PM) but we didn't have any issue to find the key and the accommodation (the key is, just following Evan's instruction from his youtube, it is very clear). The accommodation it self is clean, spacious and homy. It is near with 7-11 (so if you need something like take away food, toiletries, milk, etc it will be very easy), Lumphini MRT Station is within minutes walk (we took 10 minutes to reach it, and most of our family member are senior above 60, and 1 7 y.o girl), and it is near with food market that sell thai traditional food and snacks near the main road.
Just one recommendation, if there is any exhaust fan inside the bath room in 3rd floor it will be very comfort (since it is stuffy)
And for Evan, the owner of this accommodation, you are very accommodating.
I would recommend Evan's house to others.
